It's good to remember what the Bullish Percentage tells us; as Dorsey says, it is a measure of risk not performance. Dorsey emphasizes this; that the Bullish Percentage tells us the overall direction of the market and the risk level of going long or short, as the case may be. Currently, the $BPNDX is at 40 and in Xs, which means we have "good field advantage" and the upside potential is greater than the downside. The likelihood of further gains should be assumed until it reverts into Os.
For trading the daily charts (not the intra day charts) the bullish percentage is a very reliable way to go.
